Answer: Option 'a' is correct.

Step-by-step explanation:

As we know about the discriminant value i.e.

if we have given a quadratic equation :

ax^2+bx+c=0

then,

discriminant value will be

b^2-4ac

There are 3 properties regarding discriminant value as follows:

1)b^2-4ac>0\\\\means,\\\\\text{ there exists real zeros}\\\\2)b^2-4ac=0\\\\means,\\\\\text{ there exists equal zeroes}\\\\3)b^2-4ac

So, here we need a zero real number solutions i.e. there does not exists any real number.

So,

b^2-4ac=-5

Hence, Option'a' is correct.

What is the perimeter of the parallelogram to the left?
zhuklara [117]
A parallelogram is a polygon that has opposite side parallel and congruent. If you already know that two of the side lengths is 8 cm and 9 cm, the other two sides will also be 8 cm and 9 cm because it has 2 pairs of congruent sides. 8+8+9+9=34 cm for the perimeter.
